Product Description 12 string solar box monitor device with built-in hall effect CT for array pv combiner box
12 string solar box monitor device with built-in hall effect CT for array pv combiner box is specially designed for smart PV combiner box. It is used for monitoring the running state of solar panels in solar cell arrays,monitoring of string
current,SPD states,cabinet temperature,dc circuit breaker states and relay contract output.
It is with sensor interface such as wind speed, temperature, irradiator, etc.
The device is equipped with Modbus over RS485 communication port for transmitting all the datas to master device.
